Neutron star g-modes in the relativistic Cowling approximation
Neutron star g-modes in the relativistic Cowling approximation
Mature neutron stars are expected to exhibit gravity g modes due to stratification caused by a varying matter composition in the high-density core. By employing the BSk equation-of-state family, and working within the relativistic Cowling approximation, we examine how subtle differences in the nuclear matter assumptions impact on the g-mode spectrum. We investigate the possibility of detecting individual g-mode resonances during a binary inspiral with current and next-generation ground-based detectors, like Cosmic Explorer and the Einstein Telescope. Our results suggest that these resonances may be within the reach of future detectors, especially for low-mass stars with M≲1.4M⊙

Abstract
Mature neutron stars are expected to exhibit gravity g modes due to stratification caused by a varying matter composition in the high-density core. By employing the BSk equation-of-state family, and working within the relativistic Cowling approximation, we examine how subtle differences in the nuclear matter assumptions impact on the g-mode spectrum. We investigate the possibility of detecting individual g-mode resonances during a binary inspiral with current and next-generation ground-based detectors, like Cosmic Explorer and the Einstein Telescope. Our results suggest that these resonances may be within the reach of future detectors, especially for low-mass stars with M≲1.4M⊙
